  De Novo Asymmetric Synthesis of an α-6-Deoxyaltropyranoside as Well as its 2-/3-Deoxy and 2,3-Dideoxy Congeners

  摘要：

  A highly divergent de novo asymmetric synthesis of benzyl alpha-6-deoxyaltropyranoside, benzyl alpha-ascarylopyranoside, benzyl alpha-amicetopyranoside, and benzyl a-digitoxopyranoside has been achieved via I common pyranone intermediate. The routes rely upon it palladium(0)-catalyzed glycosylation reaction and corresponding post-glycosylation transformations, The control of the absolute and relative stereochemical configuration came from a Noyori reduction of 2-acylfuran and subsequent diastereoselective introduction of other stereogenic centers.

  使用钯催化的糖基化反应从头合成寡糖

  摘要：

  使用钯催化的糖基化反应从呋喃醇合成天然的全 d-和/或非天然的全 1,4-和 1,6-寡糖。1,4- 和 1,6-α-甘露糖-二糖是从手性呋喃醇开始的七个总步骤中获得的。类似地，1,4-和1,6-α-甘露糖三糖也分九个总步骤合成。该过程整体效率的关键是使用高度非对映选择性钯催化的糖基化、还原和二羟基化。

  The macrocyclic antibiotic mangrolide A has been described to exhibit potent activity against a number of clinically important Gram‐negative pathogens. Reported is the first enantioselective total synthesis of mangrolide A and derivatives. Salient features of this synthesis include a highly convergent macrocycle preparation, stereoselective synthesis of the disaccharide moiety, and two β‐selective

  alcohols using a palladium-catalyzed glycosylation reaction. The 1,4- and 1,6-alpha-manno-disaccharides were achieved in seven total steps starting from chiral furan alcohols. Similarly, 1,4- and 1,6-alpha-manno-trisaccharides were also synthesized in nine total steps. Key to the overall efficiency of this process was the use of highly diastereoselective palladium-catalyzed glycosylations, reductions,
